KEGG - OVERVIEW
The KEGG PATHWAY database is a collection of graphical diagrams (KEGG pathway maps) representing molecular interaction networks in various cellular processes. Each reference pathway is manually drawn and updated. Organism-specific pathways (green-colored pathways) are computationally generated based on the KO assignment in individual genomes.

Database Description
BioModelsA database of annotated biological models that allows biologists to store, search and retrieve published mathematical models of biological interests.
Reactome
A curated database of biological processes in humans. Reactome will not only be useful to general biologists as an online textbook of biology, but also to bioinformaticians for making new discoveries about biological pathways.

BIOCARTA PATHWAYS
Observe how genes interact in dynamic graphical models. Our online maps depict molecular relationships from areas of active research. In an "open source" approach, this community-fed forum constantly integrates emerging proteomic information from the scientific community. It also catalogs and summarizes important resources providing information for over 120,000 genes from multiple species. Find both classical pathways as well as current suggestions for new pathways.
